Developers made this game for watching ads. There aren’t any winable level without watching ads or spending money. This is a really nonsense . I’m tester and I know that testing this game was only checking lines for watching ads was really working or not.. The main idea and desire of the creators of this application was probably to make money from this game, not from playing it, but from advertising. They were forced to watch not one but 22,440 ads in 19 out of 20 rounds. It's interesting that the testers also watched ads?! :))
